Adaptive Digital Technologies, Inc.

IP phone/intercom/ATA for OMAP3530, OMAP3730, DM814X, DM816X, and Stellaris® devices.

Supported TI Processors: DaVinci™ DM81x processor, DM81x Video SoC, DM814x, DM816x, OMAP35x, OMAP3525/30 SoC, Stellaris® ARM® Cortex™-M based MCUs: 3000 Series

Adaptive Digital simplifies software design of an IP Phone, IP Intercom or ATA. We provide the software that runs on the DSP consisting of a fully functioning and complete SIP solution with RTP, UDP/IP, G711, G.729AB, tone handling, and echo cancellation. Additionally we offer what we call ISS (Intercom Server System), which is a software component that runs on the ARM under Linux. The ISS deals with the DSP interface and control, and RTP streaming over UDP/IP. The ISS also provides an interface to your ARM-based application.

Adaptive Digital’s ISS software subsystem simplifies software design of an IP intercom or IP phone that runs on TI’s OMAP3530 and DM814x/DM816x devices. ISS implements complete VoIP capability all the way from PCM to Packet and back. This includes a process running on the ARM under Linux as well as the necessary voice-processing running on the DSP core.

Adaptive Digital’s ATA solution is a software and hardware reference design that provides equipment manufacturers a fast path to market for a low-cost ATA. The application runs completely within the Stellaris® MCU’s internal flash memory and RAM. A Silicon Labs ProSLIC™ provides the FXS line interface and a Codec as well as POTS protection circuitry that typically requires additional circuitry. Stellaris MCU-based ATA and IP Phone software solutions share a similar base set of protocols and algorithms while separately addressing the features that are unique to these two solutions.
